FRANK W. EVELAND, OF HOT SPRINGS, ARKANSAS.

LIQUID-FUEL BURNER.

u Specification of Letters Patent.

App1ication iiledMay 24, 1913. Serial No. 769,706.

To all whom it may concern Be it known that I, FRANK W. EVEL'AND, a citizen of the United States, residing at Hot Springs, in the county of Garland and State of Arkansas, have invented certain new and useful Improvements in Liquid- Fuel Burners, of which thefollowing is a specification.

lVIy invention relates to burners which utilizeliquid fuel as the heating medium and which liquid fuel is vola-tilized or converted into a gas by passage through a retort in a heated state prior to ignition.

The main object of my invention is to provide a construction wherein substantially complete combustion will take place to the end that but a very inappreciable carbon or soot deposit will take place in the retort and burner, avoiding the necessity of frequent cleaning of the parts.

In carrying out the said objects, important objects are to construct a device of this character that will be highly eifective in operation, durable in use, simple in construction and capable of manufacture at minimum cost.

Another import-ant object of the invention is to provide a regulating eans for the supply of air tothe burner employed.

With the foregoing and additional objects in View, such as will appear hereinafter from the followingdescriptiontaken in connection with the accompanying drawings, one approved form of the invention is disclosed.

In said drawings: Figure 1 is a side view in elevation of the burner; Fig. 2 is a top or plan view of the starting pan of the burner; Fig. 3 is a longitudinal sectional view through the said starting pan, showing fragmentarily in connection therewith, the burner; andFig. 4 is a detail vertical. sec tional view through the retort coil.

Referring specifically to the drawings, the main supply .pipe'connects to the burner structure at the coupling or joint 1. From this joint 1 rises an upstanding conduit pipe 2 connected to a valve 3, inturn connected to a substantially horizontally disposed intake or crown portion 4 of a retort 5 formed of a plurality of hollow helical coils 5. The valve 3 is operable to control thesupply of fuel from the supply ipethrough the crown pipe 4. The retort COIlS define between them a space centrally of which is connected to the lowermost coil an elbow 6 which is in turn connected to an elongated burner pipe .pipe 7 is 7, which body extends on opposite sides of the elbow 6, diametrically of the coils. On each of opposite sides of the elbow 6, burner provided with an outlet orifice 8 for fuel.

A starting pan designated 9 is employed and this pan has end walls 10 rising therefrom provided with notches 11 in which the burner pipe 7 rests. Also the starting pan is provided with openings 12, one below each burner orifice 8, said openings being surrounded by frusto-conical hoods 12, the

latter having notches 13 at their top in which the'burner pipe 7 also rests. In each hood is mounted a damper 13, each of which is preferably constructed of cast iron, and which areconnected to a rod 14 turnail mounted in the hood and being provided wit-h a handle at 15 to facilitate adjustment of the dampers. Suspended from the crown pipe portion 4, by means of two bolts 6' are circular deflector plates 8 which are fastened to the bolts by means of nuts 7 An auxiliary nether fuel supply pipe 16,is employed and leads from the coupling 1, having connectedthereto a valve 17 to control the su ply of fuel therethrough.

In t e operation of the burner, with the valve 3 closed, valve 17 is opened whereupon a proper amount of liquid fuel flows ,into the starting pan. Thereupon said valve 17 is closed and the fuel is ignited, the flame produced effectively heating the retort 5. When the retort 5 has been sufilcientlyheated to convert liquid fuel to a gas, valve 3 is opened, and liquid fuel then passes from the supplypipe through the coupling 1, through pipe 2, valve 3, crown'portion of pipe 4 and through the coil 5, being vaporized while in the coil 5, and issuing from the cpil through the coupling 6 into the burner pipe 7 and out of. the orifices 8. At this stage the flame from the pan 9 persists and ignites the fuel issuing from the orifices, the flames from the said orifices rising in the space defined by the retort and effectively heating the retort so that as the fuel is supplied, it will be effectively vaporized or volatilized before issuance through the orifices 8. Dampers 13 are operable to control the amount of air admitted to the burner.

It is to be understood that merely the preferred embodiment of the invention has been illustrated and described and that changes may be made within the spirit and scope thereof.

Having thus described my invention what I claim is':-

1. In a device of the character described, a supporting structure provided with an up standing hood surrounding an air-intake 0pening,said hood having notches at its top, a burner member seated, in said notches, said member having a burner orifice adjacent the top of and within the limit of the hood, and a continuous coil forming a retort section over. the hood and located above and in communication with said burner member and arranged to be heated by the flame issuing from the burner orifice.

2. In a device of the character described, a supporting structure provided with an upstanding hood surrounding an air-intake opening, said hood being rusto-conical in shape, a. burner member mounted adjacent the top of said hood havin a burner'orifice adjacent the top of and wlthin the limit of the hood, a damper within the hood, means for operating and supportin the damper rotatably mounted in the hoo and a retort section above and in communication with said burner memberand arranged to be heated by the flame issuing from the burner orifice. I

3. In a device of the character described, asupporting structure provided with an upstanding hood frusto-conical in shape and surrounding an air-intake opening, said hood havingnotches, a burner memberseated in said notches, said member having a burner orifice adjacentthe top of and within the limit of the hood, a damper within the hood, a rod supporting the damper turnably mounted in said -hood,vand a continuous coil forming a retort section over the hood, located above and in communication with said burner member, and arranged to be heated by the flame issuing from" the burner orifice.

In testimony whereof I afiix my signature in presence of two witnesses.
